Compare the basic strengths of ortho, meta and para isomers of nitroaniline and predict the decreasing order of basicity

Explanation

To compare the basic strengths of ortho, meta, and para isomers of nitroaniline and predict the decreasing order of basicity, we will analyze the structure and the electronic effects of the nitro group (-NO2) on the amino group (-NH2) in each isomer.

### Step 1: Understand the structure of nitroaniline isomers
- **Ortho-nitroaniline**: The amino group (-NH2) is adjacent to the nitro group (-NO2).
- **Meta-nitroaniline**: The amino group is separated by one carbon from the nitro group.
- **Para-nitroaniline**: The amino group is directly opposite the nitro group on the benzene ring.

### Step 2: Analyze the electronic effects
